Mean Genes: From Sex to Money to Food Taming Our Primal Instincts

Genes are credited or blamed these days for more and more human behaviors and predicamentsDbut gambling, courtesy and even greed? Phelan, a professor of economics at Harvard, and Burnham, a biology professor at UCLA, focus not on the mechanisms of particular genes but on the effects of more general evolutionary patterns. In this enormously entertaining sociobiological overview, they argue that humans are well adapted to the environment in which we originated, but since we are no longer hunter-gatherers, instincts that evolved under those conditions can lead to harmful excess in today's world. Obesity, for example, occurs because early humans faced food shortages and adapted to store fat in their bodies. Burnham and Phelan explain the evolutionary basis for such troublesome matters as overspending, gambling, drug abuse, sexual infidelity, rudeness and greed. The point, they emphasize, is not to excuse harmful behaviors, but to understand that they are part of our animal natures. This approach, they believe, enables us to find better ways to cope with these problems than mere willpowerDin their view, a tactic doomed to failure since it runs counter to instinct. Burnham and Phelan cite their own amusing strategies for dealing with food and gambling problems, and insist that anyone can learn to ""tame"" their ""mean genes."" Though this book only scratches the surface of a subject considered in detail by such scientists as E.O. Wilson, Richard Dawkins and Sara Blaffer Hrdy, it is sure to generate wide popular interest.
